Specification of Letters Patent.

'fatented May 22, 1906.

Application filed October 4:. 1905. Serial No. 281,338.

To all whom, it may concer-71,:

Be it known that I, BENJAMIN Crow, a citizen of the United States,residing at Dalton, in the county of Berkshire and State ofMassachusetts, have invented a new and useful Swing, of which thefollowing is a specification.

This invention relates to swings, more particularly to the largerapparatus of this character requiring outside power to operate them, andhas for its object to improve the construction and increase theefciency, utility, and safety of devices of this character.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the invention consists in certainnovel features of construction, as hereinafter fully described andclaimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of the embodiment of the inventioncapable of carrying the same into practical operation.

In the drawings, Figure 1 is a front elevation, partly in section, ofthe improved apparatus. Fig. 2 is an end elevation of the same, alsopartly in section. Figs. 3 and 4 are views similar to Figs. 1 and 2,illustrating modifications in the construction of some of the parts.Fig. 5 is a plan view of the construction shown in Figs. 3 and 4 with aportion of the platform broken away to illustrate the arrangement of theparts beneath. Fig. 6 is a transverse section, enlarged, of thesupporting structure. Fig. 7 is an enlarged detail of one of thecarrier-wheel-adjusting devices.

In the improved device is comprised a supporting structure or tower,preferably formed of longitudinal bars. 10, arranged in pairs and eachpair spaced around supporting-hoops 11, to which the bars are riveted,the hoops being arranged at as frequent intervals as required to securethe requisite strength and stability.

The construction of the tower is illustrated more fully in Fig. 6, whichrepresents an enlarged transverse section of the same. The tower will beof any required height and size and will terminate at the lower end in abase 12, preferably of iron and suitably supported by braces 13, thewhole embedded in concrete, (indicated at 14.) Extending laterally fromthe tower near the upper end is a bracket or frame 16, having arelatively large pin or shaft 15, forming a journal in verticalalinement above the track. Disposed upon the ground (represented at 17)is a track 18, curved concentrically to the pin 15 and suitablysupported, as at 19. Disposed above the track 18 is a car or carriage20, having bearing Wheels 21, running constantly upon the track. Thewheels are provided with means, such as standards 22 vand set-screws 23,for adjusting them vertically relative to the tracks 18, as hereinafterexplained. Attached to the pin 15 is a circular frame 24, over which anelongated U- shaped suspension member 25 bears and connected by its endsat 26 27 to the car. The suspension member is connected rigidly to thecircular member 24 by clips 28 or by other suitable means. The bracket16 thus overhangs the track and supports the car in position to be movedback and forth over the track and produces the required swingingmovement without side strains upon the car or track. The approach to thecar is thus without obstructions from one side, and all danger of theoccupants of the car being injured by contact with the supportingstructure is materially reduced.

Any suitable power may be employed to operate the car and willpreferably be applied to the suspension element below the circularmember 24--as, for instance, to an arm 29, attached transversely of thesuspension element, as shown in Figs. 1 and 2, the operating memberbeing indicated at 30. Numerous ornamental bars 31 may be attached tothe circular member 24 and suspension member 25, as shown in Figs. l and2, and supplied with rcolored lights in the cavities 32 to increase thepleasing appearance of the device.

In Figs. 3, 4, and 5 a modified structure is shown wherein two of thecurved tracks are shown with the bearing-wheels 21 centrally of the car20 and provided with a slightly different means for adjusting theWheels, as represented in Fig. 7, consisting in frames 38, having blocks39 slidable therein and each provided with a bearing for the shafts ofthe wheels 21, the frames having adjusting-screws 40 41 bearing uponopposite sides of the blocks and by means of which the wheels may beadjusted relative to the carriage'20, and thus maintain the same in posiIOO IIO

tion relative to the segmental track 18. In the modified structure alsoa platform 33 is shown connected to the supporting-tower and adapted forcarrying a motor 34, preferably electric, and connected by rods 35 36and bell-crank 37 to the circular member 24. By this means when themotor is operated the suspension member is also operated and the carmoved back and' forth over the curved track. The car is thus operatedwith safety to the occupants, as no matter how rapidly the car may bemoved there is no danger from accidents, as the track 18 effectuallyprevents any tendency of the car to fall or become displaced.

Having thus described the invention, what is claimed is- 1. In a deviceof the class described, a supporting structure, a bracket-frame eX-tending laterally from said structure, a shaft carried by saidbracket-frame and provided with a bearing extending beyond the same, atrack curved concentric to said shaft and in vertical alinement with thebearing thereof, a car having wheels bearing upon said track, andconnecting means between said car and bearing.

2. In a device of the class described, a supporting structure, abracket-frame eX- tending laterally from said structure, a shaft carriedby said bracket-frame and provided with a bearing extending beyond thesame, a track curved concentric to said shaft and in vertical alinementwith the bearing thereof, a car having wheels bearing upon said track, asegmental member swinging upon said bearing, a IU-shaped hanger bearingover said segmental member and coupled at the terminals tov said car,and coupling means for clamping said hanger to said segmental member.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
